You can use
overload-queue-length = 1
That way new requests will be answered from the cache.

P.S: Make sure caching is enabled in pdns
If you have high end machines, you can think of increasing max-queue-length

Hello,
PDNS Auth server is crashing with the message:
5016 questions waiting for database attention. Limit is 5000, respawning
Configuration:
pipe-backend over unix-socket as pipe-command=/tmp/xyz.sock.
max-queue-length=5000
Any kind of help will be highly appreciated.
Thanks and regards,
